Since personally developing the dripping technique, paintings by JOH (a.k.a. Jorge Humberto) resemble 3D sculptures.

Humberto's paintings are executed on wooden, canvas and paper supports, each with a different and unique shape. The support is coated with a mix of pigment and oil; this mix is dripped in hundreds of fine lines that – while creating the illusion of tridimensionality – give the work a texture similar to fabric.
'Every work needs a different gesture, determined each time by the shape of the support,' explains Humberto, who painstakingly executes each piece by hand. He says his creations question the definition of a sculpture. 'Is it a 3D painting or a 2D sculpture,' he asks.
